The earliest toy trains were made from lead and had no moving parts. Some had wheels that turned, but these needed to be pulled or pushed. A few of the early 19th-century push toy trains were made from tinplate, like the large, durable, stylized locomotive toys from the U.S., which were painted gold and red and decorated with hearts and flowers. model trains dc
Around 1875, technological improvements in materials and manufacturing allowed tin to be scraped, cut, rolled, and lithographed faster than previously.
Toy trains were altered when Märklin, a German company which specialized in doll house accessories, sought to create an equal toy for boys where a continuous revenue stream could be guaranteed by selling add-on accessories for decades after the initial purchase. In addition to boxed sets containing a train and track, Märklin offered additional track, rolling stock, and buildings offered separately, creating the predecessor to the modern model train layout featuring scenery and buildings in addition to a working train.
Electric trains adopted, with the first appearing in 1897, made by the U.S. company Carlisle & Finch. As residential use of electricity became more common from the early 20th century, electrical trains gained popularity and as time went on, these electrical trains grew in sophistication, gaining lighting, the ability to change management, to emit a whistling sound, to smoke, to remotely couple and uncouple cars as well as load and unload freight. Toy trains by the first half of the 20th century were often made of lithographed tin; later trains were often made mostly of plastic.
Pull toys and wind-up trains were marketed by children, while electric trains were marketed towards teens, particularly teenaged boys. It was during the 1950s the modern emphasis on realism in model railroading began to grab on.
Today, S gauge and O gauge railroads are still considered toy trains by their own adherents and are often accessorized with semi-scale model buildings by Plasticville or K-Line (who owns the rights to the Plasticville-like buildings created by Marx from the 1950s into the 1970s). However, due to their high cost, one is more likely to locate an HO scale or N scale train set at a toy shop than an O scale collection.
Many modern electric toy trains comprise sophisticated electronic equipment which exude digitized sound effects and allow the operator to safely and easily run several remote controller trains on a single loop of track. In recent years, many toy rail operators may operate a train using a TV camera at the front of the engine and hooked up to a screen, such as computer monitor. This will show an image, like that of a genuine (smaller size) railroad)
